  13           Note that the answer to this question doesn't directly affect the
  14           kernel: saying N will just cause the configurator to skip all
  15           the questions about Realtek devices. If you say Y, you will be asked for
  16           your specific card in the following questions.

  24         ---help---
  25           This is a network (Ethernet) device which attaches to your parallel
  26           port. Read the file <file:drivers/net/ethernet/realtek/atp.c>
  27           if you want to use this.  If you intend to use this driver, you
  28           should have said N to the "Parallel printer support", because the two
  29           drivers don't like each other.

  40           This is a driver for the Fast Ethernet PCI network cards based on
  41           the RTL8139C+ chips. If you have one of those, say Y here.
  42
  43           To compile this driver as a module, choose M here: the module

  51         ---help---
  52           This is a driver for the Fast Ethernet PCI network cards based on
  53           the RTL 8129/8130/8139 chips. If you have one of those, say Y here.

  55           To compile this driver as a module, choose M here: the module

  61         depends on 8139TOO
  62         ---help---
  63           This instructs the driver to use programmed I/O ports (PIO) instead
  64           of PCI shared memory (MMIO).  This can possibly solve some problems
  65           in case your mainboard has memory consistency issues.  If unsure,
  66           say N.
  67
  68 config 8139TOO_TUNE_TWISTER
  69         bool "Support for uncommon RTL-8139 rev. K (automatic channel equalization)"
  70         depends on 8139TOO
  71         ---help---
  72           This implements a function which might come in handy in case you
  73           are using low quality on long cabling. It is required for RealTek
  74           RTL-8139 revision K boards, and totally unused otherwise.  It tries
  75           to match the transceiver to the cable characteristics. This is
  76           experimental since hardly documented by the manufacturer.
  77           If unsure, say Y.
  78
  79 config 8139TOO_8129
  80         bool "Support for older RTL-8129/8130 boards"
  81         depends on 8139TOO
  82         ---help---
  83           This enables support for the older and uncommon RTL-8129 and
  84           RTL-8130 chips, which support MII via an external transceiver,
  85           instead of an internal one.  Disabling this option will save some
  86           memory by making the code size smaller.  If unsure, say Y.
  87
  88 config 8139_OLD_RX_RESET
  89         bool "Use older RX-reset method"
  90         depends on 8139TOO
  91         ---help---
  92           The 8139too driver was recently updated to contain a more rapid
  93           reset sequence, in the face of severe receive errors.  This "new"
  94           RX-reset method should be adequate for all boards.  But if you
  95           experience problems, you can enable this option to restore the
  96           old RX-reset behavior.  If unsure, say N.

 106           Say Y here if you have a Realtek 8169 PCI Gigabit Ethernet adapter.
